GAsoLiNE FILTER.

T o all whom it may concern:

13e it known that I, LINCOLN A. ZELLER, a citizen of the United States, and a resident of New York, in the county of Bronx and State of New York, have invented a new and useful Gasoline Filter, of which the followinor is a specification.

ily invention relatesI to gasoline or liquid fuel filters and has particular reference to a filter for installation in the ipe line be-l tween the carburetor and liquid) fuel tank of an internal combustion engine.

The principal object of theinvention is to provide a liquid fuel filter that can be readily 'disassembled in order to clean or remove sedimentfrom the filtering element.

A further object of the invention is to provide a filter to be installed in the liquid fuel supply'pipe of an internal combustion engine and which is so constructed as to permit the liquid fuel to pass through the filter or, if desired, permit the liquid fuel to pass directly to the carburetor.

lVith the preceding and other objects and advantages in mind, the invention consists l in the novel combination of elements, construction and arrangement of parts and operationsv to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, wherein:

Figure 1 is a plan' view of my improved filter;

Figure 2 is a vertical sectional view of the same;

Figure 3 is a horizontal sectional view taken on line 3-3 on Figure 2; and

Figure 4-is a vertical sectional view taken on line 4-4 of Figure, 2.

Referring in detail to the drawin wherein similar characters of reference esignate similar parts throughout the several views, the numeral 5 desi aies a bowl-shaped receptacle formed init an externally threaded annular bead 6 at its upper end'. For ther bowl-shaped receptacle 5 there is provided a circular cover 7 having an annular groove 8 in its under face for the reception of the threaded bead 6, the outer wall of this groove 8 beinginternally threaded for cooperation with the bead 6. t

This cover plate 7 is cast with a vertically dis ed substantially frusto-conical valve casing 9 at' its center, and rotatable therein is a. frusto-conical valve or cock 10, the latter end of which projects below the vunder face of the cover 7. Encircling this lower end of the valve .1 0 is a coil spring 11, the lower end of which engages an annular flange 12 disposed at the lower end of the valve 10 and its opposite end bearing against the under face of the cover 7. This spring 11 holds the valve l0 against the inner face of the valve casingand thus compensates for wear between the valve and casing.

A horizontally disposed T-shaped casting 13 is formed with the upper face of the cover 7 and the sides of the valve casing 9.

One of the legs of this T-shaped casting is formed with an L-shaped passageway 14"X and the second leg is formed with an L- shaped passageway 14", both of which open into the valve casing 9.

Formed in the cover 7 upon opposite sides of the valve casing 9 and opening into this valve casing are passageways l5 and 16. These passageways 15 and 16 extend parallel to those legs of the casting 13 that are in longitudinal alinement and have communication with the passageways .14, 14x of the latter. The passageway 14xx of the remaining. leg opens into the receptacle 5. The passageway 15 constitutes an inlet and is adapted to be connected with the supply pipe from the liquid fuel storage tankl (not shown) while the passageway 16 is adapted to be connected with a pipe which leads to the carburetor (not shown).

The valve 10 is formed with a vertically disposed L- shaped opening 17 adapted to register with Vthe passageway 15 and is also provided with a horizontally disposed L- shaped opening 18 above the opening 17 that' is adapted to communicate with the passageways 16, 14xx of two legs of the casting 13 disposed at right angles to each other, as illustrated in Figure 3. f

A transverse opening 19 is provided in the valve 10v above the opening 18 and is adapted to establish communication between the passageways 14, 14x of the two longitudinally alined legs.

An annular shoulder 20 depends fromthe under face of the cover 7 and engaged with this shoulder 20 is a cylindrical reticulated or filter element 21 closed at its lower end.

When the valve 10 is in the position shown in Figures 2, 3 and 4, the liquid fuel will be discharged into the filtering element 21 by 'wa'- of the L-shaped opening 17. The liqui will then flow through the passageway ico, p

14X", the opening 18 and thence thro h the outlet paageway 16. When it is deslred to permit the liquid fuel to pass directly to the carburetor wlthout being filtered, the valve 10 will be arranged at right angles to the position shown to bring the opening 19 into registration with the passageways 14, 14* in the longitudinally alined legs.

It is to be understood that the form of my` invention herein shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the Subjoined claim.

Having thus described my invention, what I claim as new and desire to secure and protect by Letters Patent of the United States, 1s:

A gasoline filter comprising a .cover member formed with a centrally disposed vertical tapered seat, and with top, bottom and intermediate horizontally disposed passages communicating with said seat, the top and bottom horizontal passages communicating said seat and formed with a top horizontal' passage, an intermediate horizontal passa and a bottom passage extending horizonte y and thence vertically -through the base of the valve, a shoulder carried by the valve at its .lower end, a spring engaging the cover member and acting upon said shoulder, a. supporting member carried by the cover member and ada ted to suspend a lter member, and a bowl iaped receptacle threaded at its upper end to be received by a similar threaded annular Wall of the cover member.
